 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule; request for comments.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain SAP cast cylinder assemblies installed in Teledyne Continental Motors (TCM) 470, 520, and 550 series reciprocating engines, Lycoming Engines (LE) 320, 360, and 540 series reciprocating engines, Avco Lycoming (AL) 540 series reciprocating engines, and Superior Air Parts, Inc. (SAP) 360 series reciprocating engines. This AD requires removing from service certain SAP part numbered (P/N) cast cylinder assemblies installed in TCM, LE, and AL reciprocating engines. This AD also requires removing from service certain cast cylinder assemblies installed as original equipment in SAP reciprocating engines, or in certain overhauled or repaired SAP reciprocating engines. This AD results from nine separated SAP cylinder assemblies in TCM reciprocating engines and one in LE reciprocating engines. We are issuing this AD to prevent cylinder separation that can lead to engine failure, a possible engine compartment fire, and damage to the airplane.
 DATES: This AD becomes effective March 12, 2007. We must receive any comments on this AD by April 24, 2007.

SUPPLEMENTARY INFORMATION: SAP informed the FAA on July 12, 2006, that at least nine SAP cylinder assemblies installed in TCM 470, 520, and 550 series reciprocating engines and one installed in LE 320, 360, and 540 series reciprocating engines had separated at the cylinder head-to-barrel threaded interface because SAP omitted a heat treat process step during cylinder barrel manufacture. This omission resulted in higher stresses in the cylinder head-to-barrel threaded interface, leading to fatigue cracking and cylinder head separation. The lowest time-in-service (TIS) for a cylinder assembly known to have separated from this defect is 202 hours TIS. SAP isolated this defect to a specific production lot of 1,354 barrel forgings used as original equipment on SAP O-360 engines and in SAP PMA cylinder assemblies as replacement parts for various TCM, LE, and AL engine models. This AD addresses the barrels used in SAP PMA cylinders installed in the engines listed below. Cylinder Assembly Eligibility

 FAA's Determination and Requirements of This AD The unsafe condition described previously is likely to exist or develop on other TCM 470, 520, and 550; LE 320, 360, and 540; AL 540, and SAP 360 series reciprocating engines of the same type design with SAP cast cylinder assemblies that have as original equipment, or have been overhauled or repaired using SAP part numbers listed in the table above. For that reason, we are issuing this AD to prevent cylinder separation which can lead to engine failure, a possible engine compartment fire, and damage to the airplane. This AD requires removing from service installed SAP cast cylinder assemblies listed in the table above, no later than 150 hours total TIS to preclude cylinder head fatigue failure and separation at the head-to-barrel threaded interface. FAA's Determination of the Effective Date Since an unsafe condition exists that requires the immediate adoption of this AD, we have found that notice and opportunity for public comment before issuing this AD are impracticable, and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to send us any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under

                    . Comments will be available in the AD docket shortly after the DMS receives them. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. *For the reasons discussed above, I certify that this AD:* 1. Is not a “significant regulatory action” under Executive Order 12866; 2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared a summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under

 Unsafe Condition (d) This AD results from the discovery of nine separated SAP cylinder assemblies installed in TCM 470, 520, and 550 series reciprocating engines and one separated SAP cylinder assembly installed in LE 320, 360, and 540 series reciprocating engines. We are issuing this AD to prevent cylinder separation that can lead to engine failure, a possible engine compartment fire, and damage to the airplane. Compliance (e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done. Determining Which Cast Cylinder Assemblies Are Installed (f) If aircraft engine records do not list the P/N of the cylinder installed during engine overhaul or repair, visually inspect the cylinders. The affected SAP cylinder head flanges are marked: SA47000L-A1, SA47000L-A20P, SA47000S-A1, SA47000S-A20P, SA47000S-A21P, SA52000-A1, SA52000-A20P, SA52000-A21P, SA52000-A22P, SA52000-A23P, SA55000-A1, or SA55000-A20P or SL32000W-A1, SL32000W-A20P, SL32000W-A21P, SL32000WH-A1, SL32000WH-A20P, SL32006W-A1, SL32006W-A20P, SL32006W-A21P, SL36000TW-A1, SL36000TW-A20P, SL36000TW-A21P, SL36000TW-A22P, SL36000W-A1, SL36000W-A20P, SL36000W-A21P, SL36006W-A1, SL36006W-A20P, or SL36006W-A21P. Cylinder Assembly Removal (g) Remove all cylinder assemblies with a serial number of 47LE053559 through 47LF053643, or 47SE054212 through 47SF054251, or 52D0531708 through 52H0532197, or 55E05223 through 55G05289, or 32WE059006 through
